This invention relates to a machine for coating candy centers or other forms of confectionery. v

It is the general object of my invention to improve and simplify the construction of such coating machines, making them easier to operate, more accessible, and more readily cleaned of chocolate or other coating material after a run of work is completed.

With this general object in view, an important feature of my invention relates to the provision of an improved and simplified mechanism for elevating the chocolate to the upper delivery tank or flow pan.

V A further feature relates to the provision of a quickly detachable reservoir or storage tank which may be readily disengaged and,

removed for cleaning or other'purposes.

My invention further relates to arrangements and combinations of parts which'will be hereinafter described and more particularly pointed out in the appended claim.

a feed portion A, a middle or coating portion B, and a delivery portion 0. I

The feed portion A comprises a. drum 20 (Figs. 5 and 6) mounted onia shaft 21 rotatable in the machine frame F. and continuously rotatedby driving'mechanism to be described. A conveyor .belt 22 is driven by the drum 20 and is guided by a crossv bar or roll 2A, a guide-plate 25, and an outer cross ba or roll 26 (Fig. 1). i

The edge portions 27 (Fig-6) of the drum 20 are preferablyof less diameterthan the middle portionofthe drum and theedge portions 28 of the conveyorbelt- 22. are correspondingly thickened. The drum portions 27 are preferably provided with spurs or studs30, projecting outward from'the drum and received 1n pockets or recesses 31 in the thickened edge portions 28'of'the.con veyor'belt. I The belt is positively driven by the spurs 30 and is held from lateral displace- The guide plate or table 25 is mounted for vertical adjustment at its left hand end, as viewed in Fig. 5, and isprovided withan adjusting screw 33 bywhioh it may be vertically aligned with the conveyor in the coating section B of the machine, The guide bar or roll 24 is mounted on sliding blocks 34 (Fi 5) having projections 35, threaded .1 o

The roll 95 is mounted in brackets 97 (Figs. 5 and 12) which are secured by bolts 98 (Fig. 5) to the frame F at points beyond the periphcry of the drums 42. The roll 95 is driven from the roll 94 by a sprocket and chain con,- nection 99 best shown in Fig. 12.

The rolls 94 and 95 act to support the belt 64 under the flow pan 41 and also have a wiping action by which the chocolate is caused to back up under the candy centers, thus coating the bottom surfaces thereof.

Adjusting screws 100 are provided in the rapping levers 86 to regulate the normal height of the rapping bar 43. The fan 45 is mounted above the rapping mechanism and is designed to deliver a blast of air through the nozzle 44, efiective to assist in the removal of surplus chocolate or coating material from the confectionery as it leaves the coating point and is conveyed toward the delivery end of the machine.

Delivery mechanism bars 104 and 105 and over a guide-plate 106,

all substantially similar to the corresponding parts in the feeding mechanism A previously described. Theouter guide-roll 105 may be adjusted longitudinally to vary the tension of the belt by an adjusting screw 107 (Fig. 2) and the inner guide-roll 104 may be similarly adjusted by an adjusting screw 108 (Fig. 3). The guide-plate 106 may be raised or lowered by means of the vertical adjusting screw 110. The belt 102 and drum 103 may be similar in construction to the belt 22 and drum 20 previously described, and the drum 103 is mounted on'a shaft 112 continuously rotated by driving connections to be described.

improved coating machine, I will now describe the mechanism for actuating the same.

the rapping cam shaft 90, all in predetermined speed relations.

Having made clear the details of construc-- tion and operation of my improved coatin machine, it will be seen that I have provide 7 a simply and conveniently operated machine, all parts of which are readily accessible and so constructed that they may be easily cleaned of chocolate and removed from the machine when so desired.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim,but what I claim is A coating machine comprising side frame members, a storage tank supported between said members, a flow pan, a pair ofdrums rotatable in vertical planes between said members and each having a portion of its peripheral path dipping within said'storage tank and a portion elevated above said flow pan, each of said drums having a rim offset toward said flow pan and overlapping the adjacent end of said pan, brackets secured to each side frame member and projecting inward over and beyond said offset rims, an arm depending from each of said brackets and having a horizontal aperture, a separate scraper bar slidable in each of said apertures with its operative end positioned within one of said offset rims, and means to secure said bars in adjusted position in said arms, whereby the feed of coating material may be regulated. V

In testimony whereof I have hereunto, affixed my signature.

A motor 120 (Fig. l) is mounted on the 2 frame F and rotates a sprocket 121 (Fig. 4) which is connected by a chain 122 to a large sprocket 123 on the rapping cam shaft 90. A small sprocket 124 on the shaft 90 is connected by a chain 125 to a large sprocket 126 on the shaft 72 which support and rotates the drums 42. A small sprocket 127 on the shaft 72 is connected by a chain 128 to a larger sprocket 129 on the guide roll 84, which in turn is connected by a small sprocket 131, chain 132 and larger sprocket 133 to the shaft 21 which rotates the feeding conveyor drum 20. A second small sprocket 135 on the shaft 72 is connected by a chain 136 to a larger sprocket'137 on the driving OSCAR E. snennvf
